Write plug-ins to handle the problem of this delivery

I have written a global Toast plug-in for vue. One of the functions is to provide an api to pass a callback function after the toast disappears, similar to using

like this.
this.$toast({
    callback(){
        this.$router.push("/")
    }
})

but the this cannot be passed when it is implemented.
the current approach is to use a new global Vue instance via $emit/$on, but it feels like this will couple the toast plug-in with the business code. I"d like to ask how to solve this problem
